Hello, my feedback won't be as smart as most people posting here but this is regarding about PU and their FS.
Basically I've been thinking why not allow PU to move while on FS? As downside to that, their movement speed is reduced and they cannot bike while the buff is on just like carrying the flag in AK.
It's been bothering me that most classes has their own offensive / defensive buffs and can freely move but why does PU needs to be pinned on the ground, knowing that they aren't even that tanky, unless inside the cocoon but that's another factor that's restricting their freedom because of how limited the range of the cocoons is.
Unlike DE or CB that can use their defensive buffs first and use their offensive buff when convenient for them depending on the situation. Then on a mass PVP, PU's literally try to use FS on a safe spot than getting close for full potential damage, but then using FS is also like a suicidal note for PU's due to how they can also be hooked and spotted easily by attackers as well as they don't get the chance to realign themselves once they use FS and enemies are not in range, thus they'll just disable FS then move and wait for the next CD to use it again.
Another thing to compare is PU and SE. For me, SE is even more of a "ranged destroyer" than a PU. They have crit, crit-atk, detection, acc and movespeed buffs, they have ranged stun, slow & debuffs and they can move really fast. Plus that OP trap that they can put anywhere (It's literally like them planting an overpowered PU that's invisible).
Lastly, I'm only basing most of this to what happened on PU at this patch, but the general idea is there.
